颞下颌关节紊乱综合征与错合的相关关系Logistic回归分析

Logistic regression analysis of temporomandibular disorders and malocclusion

目的探讨颞下颌关节紊乱综合征与错合的关系。方法 2003—2007年间前来第四军医大学颞下颌关节门诊被诊断为颞下颌关节紊乱综合征,连续病例613例(TMD组),2007—2012年间前来空军临潼航空医学鉴定训练中心口腔科单纯牙列不齐要求正畸治疗的连续病例682例。记录各病例错合情况,对2组人群作配对多因素条件Logistic回归分析。结果共配对276对,进入Logistic回归模型的因素有对刃合、前牙反合、后牙反合、锁合,OR值分别为0.523、0.270、1.824、1.946。结论对刃合、前牙反合、后牙反合及锁合与颞下颌关节紊乱综合征有相关关系,其中影响美观的前牙异常正畸治疗需求高,后牙反合、锁合是危险因素,后牙异常可能易患TMD。

Objective To investigate the relationship between temporomandibular disorders（TMD） and malocclusion.Methods The TMD group included 613 patients diagnosed TMD in department of oral anatomy and physiology,the fourth military medicai university.The control group included 682 patients in department of stomatology,lintong clinical aemspace medicine who sought orthodontic treatment because of pute irregular dentition since 2007-2012.The malocclusions of the patients were recorded.The patients of the two groups were analyzed by the paired multivariate logistic regression.Results Match 276 pairs in all The factors including edge to edge occlusion,anterior crossbite,posterior crossbite,scissors bite were took into the logistic regression model.The odds ratio was 0.523,0.270,1.824,1.946.Conclusion Edge to edge occlusion,anterior crossbite,posterior crossbite,scissors bite were associated with TMD.The one with abnormal anterior teeth that infecting his appearance is more will to accept orthodontic treatment.Posterior crossbite,scissors bite were risk factors.The one with abnormal posterior teeth is easy to suffer from TMD.
